Solving Client-to-Cluster Connectivity Problems
Problem
Clients cannot access a group
that has failed over.
Troubleshooting the Compaq ProLiant Clusters HA/F100 and HA/F200 6-15
continued
Possible Cause
Networking problem.
Action
1. Ensure a physical
connection between the
clustered nodes exists.
2. Verify the network cabling is
not damaged or loose on the
surviving node.
3. Verify MSCS was able to
receive the heartbeat of the
surviving node and properly
failed over the resources.
4. Verify the failed over group
is a virtual server (that is,
the group contains an IP
address as a resource).
5. If a hub joins the clients to
the cluster, check the
physical connection between
the clients and the hub and
between the hub and both
cluster nodes.
